Authorities are pausing recovery efforts for the four additional people who are presumed dead after the bridge collapse, Col. Roland L. Butler Jr., the superintendent of Maryland State Police said Wednesday evening.
“At this point, based upon the conditions, we are now moving from a recovery mode to a salvage operation," he said.
"Because of the superstructure surrounding what we believe were the vehicles and the amount of concrete and debris, divers are no longer able to safely navigate and operate around that," he said.
"We have exhausted all search efforts."
The superintendent added that based on sonar scans, officials believe that the vehicles are "encased in the superstructure and concrete" of the bridge.
Butler Jr. added that there is "no definitive timeline" for how long the salvage phase will take, once it is complete, the divers will go back to the site.
“The sonar simply said they cannot get to that area because it was fully encased in the superstructure," he said. “Once that salvage effort takes place and that superstructure is removed, those same divers are going to go back out there and bring those people closure," he added.
